SCALING-MACHINE.

Specification of Letters Patent.

Patented Sept. 14:, 1909.

Application filed September 16, 1908. Serial No. 453,243.

To all'whom it may concern;

Be it known that I, CHARLES H. OVER- KAMP, a citizen of the UnitedStates, residing at Cincinnati, Ohio, have invented a new and usefulImprovement in Scaling-Mm.

chines, of which the following is a specification.

My invention relates to scaling machines for dough or other plasticmaterial and the objects of my improvements are to provide cam and levermechanism for moving the dough box and plunger intermittently and inpredetermined time relation to each other; to provide a positive clutchand lever mechanism for automatically starting and a wider range ofuses; and to provide simple and durable construction and assemblage ofparts for securing facility of operation and efiiciency of action. Theseobjects are attained in the following described manner, as illustratedin the accompanying drawings, in which Figure 1 is a longitudinalsection of a scaling machine embodying my improvements; Fig. 2, atransverse section in the line of the clutch shaft; Figs. 3 and Arespective end and front elevations of the movable clutch member showingthe position of the cams thereon, and Fig. 5, a front elevation of thedough box with partitions and cut off plate.

In the drawings, 1 represents the frame, 2 the hopper thereon, 3 thefeed rolls and 4: the dehvering apron, all constructed and arranged inthe ordinary manner. The dough box 5 is divided into a plural number ofchambers 6 by means of the partitions 7 and formed with a cut off plate8 whereby it is slidably mounted in guide grooves 9. A series ofplungers 11 formed on the same head and provided with a single stem 12are thereby movable within the corresponding chambers 6. An arm 13secured on the rock shaft 15 is connected with the dough box by means ofa link 16 and an oppositely extended arm 17 secured on said shaft isconnected by means of a pitman 18 with an eccentric 19 which is idlymounted on the driven shaft 21 for intermittently moving the dough boxinto and out of registration with the discharge opening 22 in rollchamber 23. A positive clutch member 2.4: formed with an inclined stop25 and with a short cam 26 is splined on the hub 1A of the eccentric 19and is automatically movable by means of the compression spring 27 intoengagement with the corresponding clutch member 28 which is secured onshaft 21. A bell crank lever 31 pivotally mounted on the frame by meansof a shaft 32 and movable in one direction by means of a spring 33 isprovided on one end with a stop 34 which is adjustable thereon by meansof a hand screw 35 for contacting with the anti-friction wheel 36 on theend of the plunger stem 12. An anti-friction roller 37 mounted on theopposite end of said lever is adapted to engage with the inclined stop25 for shifting the clutch member 2% on the hub 14 against the yieldingexertion of the spring 27 and out of engagement with the correspondingclutch member 28. WVhen clutch member 24 is thus disengaged from themember 28, the lip 38 thereon contacts with the anti-friction roller 37for maintaining the intermittently movable parts out of action and inpredetermined positlons.

A curved arm 41 pivotally secured at one end to the frame at 42 andmovable in one direction by means of a spring 43 terminates at its otherend in a knocker 4A and is provided with an anti-friction roller 45arranged to ride on cam 26 for moving said arm in the oppositedirection.

In operation, the feed rolls, the shaft 21 and the apron are driven atrespective constant speeds in the usual manner by driving connections(not shown). The dough is forced by the feed rolls within the chambersof the dough box under sufficient pressure to drive the plungers in arearward direction with the roller on the plunger stem into contact withthe adjustable stop 34 whereby the bell crank lever is rocked with theanti-friction roller on its opposite end out of engagement with theinclined stop on the movable clutch member. The exertion of spring 27then moves said clutch member into engage- .ment with the correspondingrotating member 28 whereby the eccentric 19 actuates the connectionstherewith to move the dough box downward into the position shown bydotted lines in Fig. 1. In the meantime bell crank lever 81 has returnedto its normal position. hen the dough box is slowly moving through itslowermost position the contact of cam 26 with the roller actuates thecurved lever with the knocker thereon into contact with the roller onthe plunger stem for moving the plunger in a forward direction andthereby discharging the scaled dough from the dough box and upon thedelivery apron. The continued movement of the eccentric 19 returns thedough box to its former position of registration with the dischargeopening 22, then the action of the lllClll'lBClStOP 25 upon the roller37 disengages the clutch members and locks the intermittently movableparts out of action.

A dough box provided with a single chamber and appropriate plunger orother forms and constrl'lction of dough boxes may be sub stituted ifdesired for the chambered bun box shown in the drawings.

Having fully described my improvements, what I claim as my invention anddesire to secure by Letters Patent of the United States is 1. In ascaling machine, the combination with the hopper, of a dough box adaptedto intermittently register with the outlet from the hopper, a plunger insaid box adapted to be moved by the dough fed into said box, a clutchmember fixed to the driving shaft of the machine, a co-acting slidingclutch member on said shaft bearing on its periphery an inclined stopand acam, an eccentric idle on said shaft but splined to the movablemember of said clutch, and means cooperating respectively with saidinclined stop, eccentric and cam for successively throwing the clutch,reciprocating the dough box and actuating the plunger to discharge thedough.

2. In a scaling machine, the combination with the hopper, of a dough-boxadapted to intermittently register with the outlet from the hopper, aplunger in said box adapted to be moved by the dough fed into said box,a clutch member fixed to the driving shaft of the machine, a co-actingsliding clutch member on said shaft bearing on its periphery an inclinedstop and a cam, an eccentric idle on said shaft but splined to themovable member of said clutch, a spring between the members of theclutch forvseparating them, a lever for engaging the inclined stop andadapted to be moved by said plunger to release said movable member ofthe clutch, a pitman connecting the eccentric with the dough-box, and alever for engagement by the cam and adapted to move the plunger todischarge the dough.

3. In a scaling machine, the combination with the hopper having alateral discharge \opening, of a slide mounted to reciprocate past saidopening and to cut off the dough passed therefrom, a dough-box dividedinto a plu ality of chambers and formed upon and movable with said slideand adapted to receive dough into said chambers when opposite saidOpening, a series of plungers adapt ed to reciprocate respectively insaid chambers, a compound clutch, eccentric, inclined stop and cammounted on the driving shaft of the machine, a pitman and levercooperating with the eccentric for reciprocating said slide anddough-box, a lever adapted to be actuated by said plungers and to engagesaid inclined stop to throw said clutch into action, and a lever forengagement by said cam and adapted to force said pl-ungers through thedough chambers to discharge the molded dough.
